Pretend She Doesn't Exist!

Two insolent stepsisters, Kimmy Kimm and Julia James, are irritated as their stepmom, Sophia Locke, has restricted their actions. To express their displeasure, they decide to retaliate against their stepmom by agreeing to disregard her existence. Unaware of Sophia having eavesdropped on their plan, communication fails when Sophia approaches and attempts to divert their attention.
Despite their initial resilience, Sophia escalates matters by engaging intimately with them, performing oral actions beside one another. Succumbing to the exposure, the stepsisters ultimately yield, leading to a reconciliatory threesome and a return to normal relations among the trio.
